For a token to retain any characteristics, it must be attached to a journal character. A raw graphic will always drop at 1x1 on the token layer, 3x3 on the map layer or at native resolution if dropped during an upload. To get the token size to stick once attached to a character 1. Size it properly and get every aspect of the token the way you want it. Then and only then... 2. Save it as the default token on a character sheet (click edit on the character journal, delete any existing token and choose the selected token as the new default. Those steps must be taken in that order. Saving the default is akin to saving your work in a word processing document. Nothing you do to the token after that will affect the default. Note also to do all of this on a page whose grid is set to 1:1. No fiddling with the scale while setting up the default or you will get unexpected results after the drag.
